SPECIFICATION forming part of Letters Patent No. 661,834, dated November 13, 1900.

i i Application led March 7, 19001 Serial No.7,671. (No model.)

To all whom it -ma/y conce-rn:

Be it known that I, GEORGE M. VILLIAMS, a citizen of the United States, residing at Santa Rosa, in the county of`Sonorna and State of California, haveinvented certain new and useful ln'lprovements in Trucks; andIdo hereby declare the followingto be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in trucks, more especially that classadapted for use in stores, Warehouses, and like business placesin readily movingortransporting barrels, boxes, dac.

It has for its object principally to provide for the readyand convenient locking and unlocking of the truck-Wheels as against turning or axial movement, as occasion may require, to provide for the ready manipulation or actuation of the lock, and to otherwise promote efficiency, facility, and utility.

It consists of the combination, with the wheels of the truck, each provided withacircular series of sockets or notches in its outer side, of a sliding or locking bar havinginturned ends adapted to engage or enter said sockets or notches, said sliding or locking bar passi ng or arranged yoke-like oversaid wheels with said ends opposed to the outer sides of said wheels, and of the details of the construction and arrangement of the parts, all

substantially as hereinafter more fully disclosed, and specificallypointed out by the Claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure l is a broken longitudinal section taken through the truck between a handled or side bar and a Wheel. Fig. 2 is a rear or underneath view thereof. Fig. 3 isa broken longitudinal section taken intermediately of the wheels.

It. will be understood thatIdo notlimit my self to details, as they may be changed without departing from the spirit of my invention and the same yet remain intact and be protected.

In carrying out my invention I employ a truck l, of the characterabove described, in its general construction such asordinarily used, with its Wheels 2, however, arranged upon their axle orfshaft Within the truckA frame or opposite the inner side of the handled or side bars thereof. In connection with said truck I use a brake or lock for the relative locking and unlocking of said wheels, comprising a transverse slidingor locking bar 3, adapted to engage said wheels, specially de signed to that end, as presently disclosed. The locking or sliding bar 1 is arranged or supported in position' within opposite skeleton castings or brackets 4, suitably secured to the handled or side bars of the truck-frame 'upon the under side. Said sliding or locking bar 3 is preferably yoke-like in construction to cause it to stand above the wheels 2, it having inturned end portions 3 reaching down and opposed to the outer sides of the wheels 2. These end portions 5a are preferably in the form of right-angled lateral or endextensions of said bar, and the wheels 2 are provided each with a circular series of-notches or sockets 5 upon the outer sides to receive or permit of the engagement therewith of the inturned free ends of said bar. These are prevented from jamming against the wheels by shoulders 6, formed upon the baritself,adapt ed to abut the brackets or castings 4 Where the bar passes therethrough. Said notches or sockets have their outer ends closed by the rims of the wheels to preventthe entrance of dirt, dmc., thereto. This bar or brakeis adapted to be held automaticallyin engagement with the notches or sockets 5 of the truck- Wheels When it is desired to prevent the latter. from turning on the axle by means of springs 7coiled or helical, secured or connected to the trlickframe and said bar, respectively. A cylindric bar or rod carrying catches 9 at a suitable interval apart, has its ends let into sockets or eyes 8 on the castings or brackets 4 to turn therein, and connected to said rod near one end and the truck-frame is a preferably coiled spring 9, the function of which will appear presently. The rod or bar 8 has a trip or projection 1U near its opposite end to provide for its convenient actuation by the foot or otherwise in axially moving said rod to disengage its catches from the locking-bar when the latter is to be released for engagement with the Wheel notches or sockets.

It will be seen that when the locking-bart;

IOO

Vzo

is withdrawn or disengaged, from the radial or lateral notches 5 of the truck-wheels,'effected by pressing down upon said bar, preferably bythe foot, sufficiently to overcome` the action or resistance of its springs, it (said bar) will be caused to pass the backs of said catches and below and be caught and be held by said catches, thus holding said bar disengaged from said wheels. During such passage ofy said bar said catches yield and instantly or automatically resume their former .or normal position to effect the retention of the locking-bar as against'the action of its springs. LOf course in order to again effect engagement of thelocking-bar with the truckwheels it is only requiredrthat sufficient pressure be applied bythe foot or otherwise to the catch-carrying rod through the trip or lug 10 thereof, said rod turning on its axes and permitting the catches to be disengaged from said bar. This disengagement of said catchesfrorn said sliding bar will allow said bar to beautomatically moved or slid into engagement with the notches orsockets of the truck-Wheels under the action of its springs, as above in-4 ti mated. y

The locking of the truck-wheels, as is desirable when loading upon the truck what-- ever weightor heavy body it may be required to move or transport thereon, aids to prevent the involuntary moving or slipping of the truck,

though it may be braced bythe foot or body of the perso.) using it, as well understood.

It will be appreciated that any desired part of one truck may be used in the lnake up of any other truck, if preferred.

Having thus fully described my invention, what I claim, and desire to secure byLetters Patent, is-

1. A truck of the character described, having its Wheels arranged within its frame, said Wheels provided, each, with a series of lateral notches or sockets on the outer-side and a sliding locking-bar adapted to laterally engage said notches, substantially as specified.

'2. A truck of the character described, having a locking-bar provided with inturned ends adapted to engage laterally the truck- Wheels, substantially as set'forth.

3. A truck of the character described, having its wheels arranged Within its frame and a sliding locking-bar having right-angled end portions or extensions adapted `to laterally engage said Wheels, substantially as set forth.

4 A truck of the character described, having its wheels provided with lateral sockets or notches, upon the outer sides, and a sliding locking-bar having right-angled end portions or extensions adaptedl to engage said notches or sockets, substantiallyas set forth.

5. A truck of the character described, having its wheels arranged within its frame, said wheels provided each witha series of notches or sockets upon the outer side, and a sliding locking-bar having right-angled end portions or extensions with their intnrned extremities' adapted to Aengage said notches or sockets, substantially as specified.

(i. In a truck of the. character described, the combination of the sliding locking-bar having inturned end portions adapted to engage laterally the truck-wheels, and a catchcarrying rod or bar with its catches adapted to engage said locking-bar, substantially as set forth.

7. In a truck of the character described,

the combination of the truck-wheels having 'lateral notches or sockets, upon the outer side, a spring-actuated locking-bar having right-angled end portions to engage' said notches or sockets and a spring-actuated catch-carrying bar or rod having its catches adapted to engage said locking-bar, substantiallyvas set forth.

8. In a truck of the character described, the combination of the wheels arranged within the truck-frame and having each a series of-lateral notches or sockets, lupon the outer side, a spring-actuated locking-bar adapted to engage said notches or sockets, brackets .0r supports for said locking-bar, secured or arranged upon the truck-frame and a springactuated rod or bar carrying catches adapted vto engage said locking-bar, said rod being axially hung upon said brackets, substantially as specied.

In testimony whereof I affix my signature in presence of two Witnesses.
